These are the most breathable sneakers available: ventilated soles and mesh uppers facilitate air circulation around your entire foot, lowering foot temperature by as much as 11º F and reducing plantar sweat by up to 50%. Recommended by the International Hyperhidrosis Society, the sneakers have perforated insoles and six vents across the outsoles that allow the bottom of your feet to breathe (where 80% of plantar sweat occurs). The in- and outsoles are buffered by a fine screen that prevents gravel from entering the shoe without inhibiting aeration. Unlike sandals that provide breathability but offer little foot support, these sneakers have a shock-absorbing, 1 1/2"-thick molded outsole, a sturdy ankle collar, and a hook-and-loop fastener for optimal foot stability while running errands or riding a bicycle. Made from neoprene (the same material used in wetsuits), the sneakers are machine washable and suitable for water sports as well as terrestrial activities. The antimicrobial footbed conforms to the foot and is naturally resistant to odor. Specify Black or White.
